Bertha is a mild-mannered Ground-type user and a member of the Sinnoh Elite Four. She aims for victory with her specialty—a steady, unyielding battle style.

A woman who somehow exudes a sense of security.
A slightly divine or auspicious feeling.
Perhaps because of this, Pokémon also seem to display abilities that are above average.
She is known as the Mother Earth Goddess.
The purpose of overlapping overlapping Bertha's jp and en name and age with Agatha is to allow viewers to imagine their relationship.
